	/**
	 * Used to transfer the net.sourceforge.cobertura.datafile property to a JVM
	 * that is about to be forked.
	 * 
	 * This is confusing, but it's required by our functional test.
	 * What happens is, we have a JUnit test that runs ant to
	 * instrument some classes.  When the instrumentation is running,
	 * we want to get the coverage info that is created by exercising
	 * our instrumentation classes.
	 *
	 * So we pass in two different coverage files:
	 * 1. The coverage data file command line parameter.  This tells
	 *    the instrument task where to write the new coverage data.
	 * 2. The coverage data system property.  This tells the
	 *    instrumentation inside the instrumented classes where to
	 *    keep track of the line hit counts, etc.
	 *
	 * @param task The Java task that will do the forking.
